CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsEasy
A global media company uses cloud services to host its video streaming platform. They experience unpredictable surges in viewer traffic during major live events. The cloud solution must automatically adjust computing resources up or down to handle these fluctuations without manual intervention. Which cloud characteristic is most critical for this requirement?
- AMeasured Service
- BResource Pooling
- COn-Demand Self-Service
- DRapid Elasticity
Show answer & explanationAnswer & explanation
Correct answer: D. Rapid Elasticity
Rapid elasticity refers to the ability of cloud resources to be quickly and automatically provisioned or de-provisioned to scale with fluctuating demand, which is essential for handling unpredictable traffic surges in a streaming platform.
Why the other options are wrong
- A. Measured service is about monitoring and billing resource usage, not the ability to scale dynamically.
- B. Resource pooling is about sharing resources among multiple consumers, not automatic scaling.
- C. On-demand self-service allows users to provision resources without human interaction, but doesn't imply automatic scaling.
Rapid Elasticity
The ability of cloud computing resources to be quickly and automatically scaled up or down to meet fluctuating demand.
- Automatic scaling of compute, storage, or network resources.
- Responds to changes in workload.
- Prevents over-provisioning or under-provisioning.
